Iridian now offers Hybrid GFFs with additional optical capabilities. For example, it can block the pump laser from light in the range of approximately 980 nm or 1480 nm while providing gain flattening for signal light amplification without the need for an additional pump wavelength blocking filter.
Moreover, Hybrid GFFs can be designed to pass or block other wavelengths in the 900 to 1700 nm band. This combined functional filter is very useful in the application of EDFA and other optical amplifier modules, which can improve the optical performance, reduce the size and the cost of the module.
